Abstract: | Coulomb excitation measurements with 16O and 4He projectiles have been performed on 160Dy, 162Dy, and 164Dy. The ground-state rotational bands up through the 8+ member were observed in the 16O experiments. The measured excitation probabilities yield B(E2; I → I ?2) values which are generally in agreement with the rotational predictions except for the 6+ → 4+ values. In each nucleus, probabilities for exciting the 2+, 4+, and 6+ members of the γ-vibrational band were measured and compared with calculated results. The B (E2; 0+ → 2+γ) values were measured in experiments involving 4He ions. The Kπ = 2? octupole band was observed in each nucleus in addition to 1? bands in 160Dy and 162Dy. Excitation probabilities were analyzed in an attempt to extract B(E3) values. |
